New grounded outlets with old wiring

I am in the process of relpacing the 2 prong outlets in my 1962 house with new 3 prong outlets. The old wiring is not grounded. If I connected the new outlet ground via ground wire to the outlet box itself...would this be acceptable (better than nothing). the old wiring is armored cable, so there would be a grounded connection to the electrical box. I tested the outlet with an outlet tester and it shower a "proper ground". Any thoughts are appreciated.

If you are sure the box is grounded then you can do what you said.

Unless the box is properly grounded (which it probably isn't) then what you have done is NOT better than nothing. You would be creating an unsafe situation, as well as violating code.

Either properly ground the receptacles, use two prong receptacles, or use GFCI protection and label accordingly.
